API RP 19B 2nd Edition, September 1, 2006
Recommended Practices for Evaluation of Well Perforators
Includes all amendments and changes through Change/Amendment , September 2006
Additional Comments: G019B2
Published By:American Petroleum Institute (API)
This Recommended Practice describes standard procedures for evaluating the performance of perforating equipment so that representations of this performance may be made to the industry under a standard practice. This document supersedes all previously issued editions of API RP 43.
Sections 1 – 4 of this Recommended Practice provides means for evaluating perforating systems (multiple shot) in 4 ways:
1. Performance under ambient temperature and atmospheric pressure test conditions.
2. Performance in stressed Berea sandstone targets (simulated wellbore pressure test conditions).
3. How performance may be changed after exposure to elevated temperature conditions.
4. Flow performance of a perforation under specific stressed test conditions.
Section 5 of this Recommended Practice provides a procedure to quantify the amount of debris that comes out of a perforating gun during detonation. The purpose of this Recommended Practice is to specify the materials and methods used to evaluate objectively the performance of perforating systems or perforators.
These procedures become effective as of the date of publication.
API REGISTERED PERFORATOR SYSTEMS
Information on API Registration of perforator systems can be found in Appendix D.
REPORTS AND ADVERTISEMENTS
Reports, articles, papers, periodicals, advertisements, or similar publications which refer to results from tests conducted according to API RP 19B must not be worded in a fashion to denote that the American Petroleum Institute either endorses the result cited or recommends or disapproves the use of the perforating system described.
Use of data obtained under API RP 19B tests in reports, articles, papers, periodicals, advertisements, or other published material shall include, as a minimum, all test configuration data not specified by API RP 19B or left to the verifying company’s choosing by API RP 19B and the average measured results of the test.
